WATCH-BOW FASTENER.

SPECIFICATION forming part of Letters Patent No. 453,843, dated June 9,1891. Application filed January 20, 1891. Serial No. 378,393. (Nomodel.)

To all whom, t may concern.'

Be it known that I, EMiL KLAHN, of Jersey City, in the county of Hudsonand State of New Jersey, have invented an Improvement in Vatch-BowFasteners, of which the following is a specilication.

My invention relates to watch-bow fasteners; and it consists of certainimprovements, which are fully set forth in the following Io specicationand are shown in the accompanying drawings, which form a part thereof.

The object of my invention is to provide a watch-case with a practical,convenient, and economical device for fastening the bow to I 5 thependant with the usual freedom of swinging movement.

In carrying out my invention I employ a bow split longitudinally throughits ends and provided upon the ends of one of its split 2o members withhooks or locking projections, which are adapted to beinserted inapertures in the pendant, and after these hooks or projections are soinserted the two members of the bow are united together in anyconvenient manner, as by solder, rivets, or screws. Vhen the two membersof the split bow are thus united, the hooks or locking projectionscannot work out of the apertures in the pendant, and the bow is thusfastened to it.

3o In the drawings, Figure l is a sectional side lelevation of awatch-case with the bow fastened thereto by my improved bow-fasteningdevices. Fig. 2 is a vertical sectional view of the same on the line m:r of Fig. l. Figs.

3 5 3, 4,- and 5 are respectively side elevations of a watch-bowdetached from the pendant, illustrating slight modifications of myinvention; and Figs. 6, 7, and S are respectively crosssectional viewsof Figs. 3, 4, and 5, Fig. 6 on 4o the line y y of Fig. 3, Fig. 7 on theline z ,z of Fig. 4, and Fig. 8 on the line w w of Fig. 5. Fig. 9 is atransverse sectional view of the bow on the line o o of Fig. 5 with themembers of the bow placed together and united.

A is the watch-case pendant, having apertures a upondiametrically-opposite sides.

B is the bow, which is split longitudinally to form two members. Uponthe ends l) of 5o the split bow B are hooks or locking projections C,carried by one of the members. In. the construction shown in Figs. 3,4f, G, and

7 these hooks or projections C are carried upon the two ends of the samemember of the split bow, while in the construction shown in Figs. 5 and8 one hook is carried by one end of each member.

In attaching the bow to the pendant the hooks C are iirstinserted intheholes or apertures, this being readily accomplished with 6o thesingle member ofthe split bow, which permits sufficient movement or playto insert the hook in the aperture. The two members of the bow are thenunited together by solder, rivets, screws, or in any other convenientmanner. lVith the two members ot' the bow thus united the playormovement of the ends ofthe bow suflieient to work the hooks orprojections C from the apertures a is prevented and the bow is fastenedto the pendant. 7o

To more effectively accomplish the fastenl ing of the bow, I prefer toform the outside of the pendant A with shoulders D, upon which the endsb of the bow seat, preventing any play or movement ot the ends when the7 5' two members of the bow are united. These shoulders may be madeeither by countersinking the outer surface of the pendant adjacentto theapertures or by employing ears. These shoulders D form sockets for thebow 8o ends l) and prevent lateral play. In Fig. 9 the two members ofthe split bow are shown united by a pin or screw (l.

lVhile it is preferable to entirely divide or split the bow B into twomembers, as shown, 8 5 it is evident that it is only absolutelynecessary to divide the bow 'at its ends, and, if desired, only the endsof the bow may be split or divided.

While I prefer'the details of construction 9o which have been hereshown, I do not limit my invention to them, as it is apparent that theymay be varied in many ways without departing from the principles of it.

NVhat I claim as new, and desire to secure by Letters Patent, is-

I. In a watch-bow fastener, the combination of a pendant having holes orapertures on diametrically-opposite sides, a bow having its ends dividedlongitudinally and pro- 10o vided with a locking projection carried byone portion of each end, said locking projection bein g adapted to beinserted in the aperture or hole in the pendant, and means to unite saiddivided portions of the bow.

2. In a watch-bow fastener, the combina.

tion of a pendant having holes or apertures on diametrically-oppositesides and provided with shoulders adjacent to said holes, a bow havingits ends divided longitudinally and provided with a locking projectioncarried by one portion of each end, said locking projection beingadapted to be inserted in the aperture or hole in the pendant, and meansto unite said divided portions of the bow.

3. In a watch-bow fastener, the pendant A, having,r the apertures a, thedivided bow B, and the hooks or looking projections C, carried by oneport-ion of each end of said divided bow, combined and operatingsnbstantially as described.

4. In a watch-bow fast-ener, the combination of a pendant formed withsockets, apertures or holes in said sockets, a bow having its endsseating in said sockets and divided longitudinally, a locking`projection carried by one portion of each of the divided ends of saidbow, adapted to beinserted in said apertures or holes in the sockets,and means, substantially as described, to unite the parts of saiddivided bow together.

In testimony of which invention I have hereunto set my hand.

EMIL KLAHN.
